MAM-A manufacturers archival grade media used around the world by photographers, hospitals, insurance companies, schools and more.

From MAM-A:

"The MAM Gold Archive Grade™ DVD-R is designed for applications requiring long-term storage of sensitive data, video or music files. The reflective layer is comprised of 24 karat gold, which allows maximum resistance to chemical breakdown -- one of the major causes of disc failure. Along with choosing the right recording dye material and bonding agent (Note: A DVD-R is made of two polycarbonate discs bonded together) the long-term stability of the reflective layer is crucial. Reflective layers using your standard "silver" surface are subject to oxidation (rust) over a long period of exposure to moisture. Unlike silver jewelry, a gold ring won't rust and neither will the gold reflective layer in this disc. In optical discs, the use of gold can triple the life of a standard disc."
